GeForce 6200A overclocking

[Andy]

I purchased this card 2 days ago and decided to overclock it.
The core speed by default is 375 and I reached 439 with the defaut fan and heatsink and the memory default speed is 532 and I reached 664, but I don't know how to test the stability of the card, in NFSU 2 and Flatout it work wery smooth and I dosn't crash but I saw some texture artifacts in the NFSU 2 menu.
Any ideeas abot program with wich I can test the stability of the card?

THANKS

I don't know how you have overclocked your card, so forgive me if I state the obvious. using "coolbits2", which you can download at 3Dguru.com. this program actually tests the safest overclock speeds for your card without damaging it. but, I would have bought a stronger card to begin with. that way extreme overclocking is not needed. just my opinion.
